This is an excellent source for info on framebuilding:

Also, the Paterek Frame Building Manual is a good step-by-step guide to frame building and the all important design of frames. It is occasionally available on ebay or by searching the online used book sellers.

United Bicycle Institute also offers a framebuilding course you could take and build your own frame during the course. I believe the frame is included in the cost of the course.

You could probably do the frame with the bunzo, but the design and prep work are all critical to the success of the frame. Do some thorough research b4 you do it.
